Description
BACKGROUND OF THE INVENTION
The present invention generally relates to a butterfly mop and,
more particularly, to a butterfly mop including a clip-on scrub
strip.
Butterfly mops are well known and generally include a mop handle
supporting a mop head including two flapper or presser plates. The
presser plates support a mop pad, such as a sponge, and are mounted
for pivotal movement downwardly and toward each other in order to
wring fluids from the mop pad. In a typical construction, a yoke
actuator is supported adjacent a rearward portion of the presser
plates and includes portions for engaging and causing the downward
movement of the plates. Such prior art butterfly mop structures are
illustrated in U.S. Pat. No. 4,864,675 issued to Jones and U.S.
Pat. No. 5,488,750 issued to Vosbikian et al.
In addition, the patent to Vosbikian shows that a scrub strip may
be attached to a sponge support member for a mop in order to
provide an abrasive material for facilitating cleaning of the
floor. Further, it is also known to provide mop pads for mops with
scrub strips mounted directly to the edge of the pads wherein the
edge of the pad carrying the scrub strip may be directed to the
floor surface for a scrubbing operation. Thus, prior art butterfly
mops generally required that an appropriate scrub strip be carried
by the mop pad and/or that the mop be rotated or otherwise
reoriented to use the scrub strip.
Accordingly, there is a need for a scrub strip for use with
butterfly mops which avoids the necessity of manipulating the
handle, such as by rotating it, to orient the scrub strip toward
the floor surface. There is a further need for a butterfly mop
incorporating a scrub strip wherein the scrub strip may be
positioned out of the way when the scrub strip is not in use, and
which conveniently positions the scrub strip adjacent to a floor
surface for a scrubbing operation.
SUMMARY OF THE INVENTION
In accordance with the present invention, a mop is provided
including an elongated mop handle, a slide grip handle slidably
received on the mop handle, an actuation yoke pivotable about a
pivot axis, and a connecting link extending between the slide grip
handle and the actuation yoke such that movement of the slide grip
handle along the mop handle causes the actuation yoke to pivot
about the pivot axis. In addition, two presser plates are mounted
to respective pivot points adjacent an end of the mop handle
wherein the presser plates support a mop pad such as a sponge.
A pair of squeeze arms defined by the actuation yoke engage and
pivot the presser plates toward each other to a mop pad squeezing
position when the slide grip handle is moved along the mop handle.
A scrub strip is located adjacent the ends of the squeeze arms and
are supported for movement with the actuation yoke between a
non-use position and an operable position wherein movement of the
scrub strip from the non-use position to the operable position
coincides with the pivoting of the presser plates toward each
other.
The scrub strip is configured to clip onto the actuation yoke and
includes a base portion, a strip of floor scrubbing material
attached to a first side of the base portion and a cover portion
attached to a second side of the base portion. A passage is defined
between the base portion and the cover portion for receiving the
actuation yoke to thereby support the scrub strip on the mop.
The yoke and scrub strip are configured such that the scrub strip
is positioned above the presser plates in its non-use position, and
is located below the presser plates and mop pad in its operable
position to engage with a floor surface.
Therefore, it is an object of the present invention to provide a
mop including a scrub strip movable between a non-use and an
operable position.
It is a further object to provide such a mop wherein the mop
includes a pair of presser plates actuated by a yoke member.
It is yet another object of the invention to provide a scrub strip
attachable to the yoke of a butterfly mop.
Other objects and advantages of the invention will be apparent from
the following description, the accompanying drawings and the
appended claims.
